IMPROVEMENT IN SMELTlNG-FURNACES.

Specification forming part of Letters Patent No. 148,371, dated March10, 1874 application filed November 15, 1873.

To all whom it may concern:

Be it known that we, JOHN H. LATEY and J OHN D.

I

The invention consists in combining an adjustable draft-pipe with themoistening-tank, into which .the smoke of smelting-furnace is passed, sothat the draft-pipe may be adjusted to a higher or lower point therein,as hereinafter described.

The drawing is a sectional elevation of two smelting-furnaces thatdischarge into a chamber or tank.

A represents the stacks of two furnaces, B B, which are curvedvso as todischarge downward into the chamber or tank G, into which water or jetsof water or steam are introduced to cause the particles of gold, silver,or lead driven off in the fumes to be precipitated. D represents theescape-pipe to the chamber, in which is placed the adjustable pipe toregulate and graduate the draft, according to circumstances. The pipe Eis made adjustable in the tank, and performs the function of determiningthe draft of the furnace.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

The combinatiomwith one or in ore furnaces, B, and a tank, 7, connectedby a stack or stacks, A, of the adjustable draft-pipe E, as and for thepurpose specified.
